Patented June 10, 1930 UNITED STATES PATENT OFFICE CHARLES H. HISER, FSPRINGFIELD, OI-IIO, ASSIGNOR TO THE SPRINGFIELD METALLIC GASKETCOMPANY, 0F SPRINGFIELD, OHIO, A CORPORATION OF OHIO CLAMPING DEVICEApplication filed November 14, 1927. Serial No. 233,123.

This invention relates to a clamping device adapted for use inconnection with metallic caskets for securing the inner top or lid tothe body of the casket in such a f' way as to furnish an air tightjoint.

One of the objects of my invention is to provide a clamping devicehaving a compressed gasket so associated with the cooperating surface asto fasten the clamping device in clamping position.

Another object of my invention is to provide a clamping device adaptedto be rotated to and from its operative and inoperative positions andwhich when in its inoperative position will be maintained in a conditionto be freely swung to its clamping position over the rim or ledge of theinner top of the casket.

In the accompanying drawings:

Fig. I is a top plan view of a portion of a metallic casket showingseveral of the improved clamping devices applied thereto.

Fig. 2 is a section on the line -a of Fig. l.

Fig. 3 is an enlarged section of some of the parts shown in Fig. 2.

Fig. 4 is a section on the line ZJ-b of Fig. 3.

Referring to the drawings, 1 represents 3u a portion of the body of themetallic casket,

the upper edge of the sheet metal sides of kwhich are inturned asindicated at 2 to provide a ledge, the inner edge of this ledge beingunited to the casket side by a sealing 35 plate 3 in the usual way. Thisinner ledge 2 forms a support both for an inner top t and for an outertop 5. It is the usual practice to clamp the inner top to the ledge 2,with an interposed sealing gasket 6 to eX- 4.0 clude air and to this endthe edge of the inner top is bent and formed to provide a rim or ledge 7to receive clamping devices carried by the main ledge 2.

Each of these clamping devices includes a e5 part constructed of sheetmetal shaped to form a lever, the arms 8 and 9 of which are arranged atright-angles to each other.

The free end of the arm 9 is bent laterally to form a foot 10, while theedges of the 5o arm 8 are bent to form the walls 11 of a pocket on theunder side of the arm to receive a packing 12 of any suitable materialpreferably felt. The inner end of the arm 8 is perforated to receive acap-screw 13, the threaded end of which projects through an aperture inthe ledge 2 and screws into the bar lll which extends the full length ofthe ledge 2 and is secured to the under side thereof by spot welding orin any other suitable way. A coil spring l5 f surrounds the cap screwand is interposed between the under side of the arm 8 and the ledge 2.

In operation, each of the arms 8 and its felt packing is turned atright-angles to the position shown to permit the inner top to be laidupon the packing 6, the spring holding the arm in raised positionagainst the head of the cap screw, after which the arm is swung to theposition shown so that the packing partly overlies the ledge 7. Thecap-screw is then tightened to cause the packing to be compressed assoon as the foot l0 contacts the ledge 2, thus forcing the ledge uponthe packing 5 to form an air tight joint.

By having a packing l2 but partly overlying the ledge 7 it will be seenthat after this packing is compressed a shoulder is formed on the undersurface of the packing which eifectively holds the clamping arm fromturning, it being necessary to unfasten the cap screw before the arm canbe swung away from the ledge. By the provision of the spring, the armand its packing, when in inoperative position, are held in raisedposition so that it is an easy matter to swing the arm 8 of the leverand its packing over the ledge 7 when it is desired to clamp the innertop to position.

Having thus described my invention, I claim:

l. In a clamping device of the character described, the combination,with a surface to be clamped, of a clamping arm having a pocket, and acompressible packing in said pocket arranged to partly overhang saidsurface when clamped thereto to form a shoulder at the edge of saidsurface.

2. In a clamping device of the character Cil described, the combination,with a surface to be clamped, of a clamping member formed of a verticalarm and a horizontal arm,

Ya clamping screw passing loosely through said horizontal arm, a supportintov which Vsaid screw is threaded, and a compressible packing carriedby said horizontal arm arranged to partly overhang said surface whenclamped thereto to form a shoulder at the edge of said surface to engagetherewith.

8. In a clamping device of the character described, the combination,with a surface to be clamped, of a clamping member, and a eompressiblemember interposed between said clamping member and said surface, saidcompressible member being arranged to partly overhang said surface whenclamped thereto to form a shoulder at the edge of said surface, toengage therewith, said clamping member having a part engaged with saidcompressible member.

In testimony whereof, I have hereunto set my hand this 25th day ofOctober, 1927.

CHARLES H. HISER.
